Abstract
A building membrane 10 for use on a corrugated metal deck comprises a sheet 12 of flexible vapour-resistant material, for example, felt, polyethylene, foil of bitumenised paper, to which are secured a plurality of members 14 of thermally-insulating material. In use, the building membrane 10 can simply be unrolled onto the corrugated surface so that the insulating members locate in the corrugations of the deck 16. <IMAGE>
Description
SPECIFICATION
Building membrane
The present invention relates to building membranes, in particular, to building membranes for use on contoured, for example, corrugated surfaces such as roofs.
It has become increasingly common for buildings to be constructed with flat roofs formed of sheets of contoured decking. Corrugated sheets are frequently used for this purpose.
Whilst flat roofs are relatively easy to construct, they give rise to problems insofar as waterproofing is concerned and, additionally, in most instances need to be provided with thermal insulation and a vapour-proof barrier layer. This has been achieved in the past simply by laying suitable sheet material in one or more layers over the corrugated decking.
In accordance with the invention there is provided a building membrane for use on a contoured surface, the membrane comprising a flexible sheet to which are secured a plurality of members of thermally-insulating material at locations such that, in use, the insulating members locate in depressions in the surface.
Where the membrane is to be used on a corrugated surface, the insulating members preferably extend transversely of the sheet at intervals along its length such that, in use, they locate in the corrugations of the surface.
Such a membrane has a number of advantages.
Because it fills the voids which would otherwise be formed between the corrugated surface and the building membrane, the thickness of thermally-insulating material above the membrane can be considerably reduced. Consequently, the upstand formed around roof-lights and the like need not be so high. With sheet material simply laid over corrugated decking,there has been a riskthata person walking overthe finished surface may step on an area ofthe building membrane over an empty space between corrugations, causing the membrane to tear. Due to the fact that there are no voids beneath the membrane of the invention, a finished surface incorporating such a membrane can be walked across quite safely with little risk of damage.
It is envisaged that the building membrane of the invention will be bonded to the contoured surface beneath using hot bitumen. Because the membrane follows the contour of the surface, a much better bond area is provided than in the case where the membrane is bonded only to the lands separating adjacent troughs of contoured surface.
The building membrane ofthe invention can, however, be rolled convenientlyforstorage because the insulating members are spaced from one another by areas of the flexible sheet material.
An embodiment of the invention will now be described in detail, byway of example, with reference to the drawings, in which:
Figure lisa schematic sectional view of the components of a flat roof incorporating a building membrane in accordance with the inventions; and
Figure2 is a partially broken-away perspective view of a building membrane in accordance with the invention in position on a corrugated metal roof deck.
As illustrated in the drawings, the invention provides a building membrane 10 comprising a flexible sheet 12 to which are secured a plurality of members 140fthermally-insulating material.
The insulating members 14areelongateand extend from one longitudinal edge of the sheet 12 to the other. The insulating members 14 are generally parallel to one another and are secured to the flexible sheet 12 at intervals corresponding to the separation of neighbouring troughs in the underlying corrugated roof deck 16. The insulating members 14 are oftrapezoidal cross-section so that they fit snugly into the similarly-shaped troughs formed in the decking 16. Where the deck corrugations are of a different shape, the insulating members are, preferably, of a suitable cross-section to conform closely to the decking surface. The insulating members may,forexample, be of cellular plastics material.They are bonded to the flexible membrane 12 either by means of a suitable adhesive material or by the inherent adhesive qualities of the membrane 12.
Due to the flexible nature of the sheet 12, the membrane can conveniently be rolled for storage.
When the membrane is to be installed, it can simply be unrolled onto the decking 16 so thatthe insulating members 14 locate in the troughs ofthe decking 16.
As mentioned above, it is envisaged that the membrane may be bonded to the decking 16 using hot bitumen. Once installed, the flat uppermost surface of the membrane 10 enables the roof to be finished in any conventional manner, for example, by the provision ofthermally-insulating roofing boards 18 and an outer weatherproof layer 20 offelt.
As mentioned above, it is desirable that the roof should be provided with a vapour-resistant layer. It is, therefore, convenient to form the flexible sheet 12 of suitably vapour-resistant material. For use in building roofs, the vapour-resistance ofthe material is preferably greater than 15 MNs/g. Suitable sheet materials are, for example, felt, polyethylene, foil or bitumenised Kraft papers.
The building membrane ofthe invention is quick and easyto instal, thus reducing labour costs, and enables a corrugated metal roof deck to be finished externally by conventional means. The finished roof can be walked on safely and requires a reduced thickness ofthermal insulation.
The building membrane of the invention can also be used to thermally insulate contoured floors and walls which may then be finished by conventional means.
